SPECIFIGATIO N forming part ofLetters Patent NO. 716,84 dated. December 2 1902. Application filed May 9, 1902. Serial No. 106,624. (No model.)

To all whom it may concern;

Be it known that 1, Donors E. SMITH, a

, citizen of the United States of America, resid- .ing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Crude-Oil Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to' makeand use the same, reference being bad to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in means for burning crudeoil, my object being to provide a device of this class which shall be simple in construction, economical 1n cost, reliable, durable, and efficient in use;

' of which will be fully understood by refer-' and to these ends the invention consists of the features, arrangements, and combinationshereinafter described and claimed, all

once to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a vertical lougitudinal section of the device, taken on the line a: at, Fig.2. Fig. -2,is a cross-section on the line 91 y, Fig. 1.

The same reference characters indicate the same parts in all the views.

.As shown in the drawings, my improved device consists of a number oftrays 5, 6, and 7, arranged one above another, and an inclined plate 8, attached to the upper tray, to

which the oil is fed in any suitable manner. As shown, the oil passes'to the inclined plate from a pipe 9, having a valve 10 for controlling the flow. The plate is preferably curved in cross section, its concave surface being uppermost to receive the oil and carry itsheavier or less volatile portion to the tray 5 below..

-. The tray 5 is connected with the plate 8 by bolts 12 and 13,'which pass through the connecte'd' parts and are surrounded by interposed sleeves 14 and 15,1arge enough to leave 'an air-space between the sleevesand the bolts, whereby the latter are protected from the heat. The sleeves also hold the plate and upper tray apart:.'-The tray5 is provided with legs 5, which engage the tray 6, the

The tray 6 is also through which the overflow passes from one tray to another. The raised parts 5 and 6 are only of suflicient height to maintain .a

shallow depth of liquid in the tray previousto the overflow from one tray 'to the other.

.The trays 5, 6, and 7Occupy a horizontal position and are provided with flanges 5 6 and 7 respectively, around their outer, edges. These flanges prevent the overflow at the edges of the trays; 1

As soonas Oil is discharged upon the plate 8 it is lighted and the most volatile portion of the oil is burned on this plate, while the heavier or less volatile. portion passes to the tray 5, where the part next in order-of volatility isburned. A portion of the heavieroil will Overflow from the tray 5 to the tray 6, where another quality will be consumed, and

if there is still .any'unconsumed oil it will pass to the bottom tray and be burned there.

It will be understoodthat difierent degrees of heat are required to burn the diiferent parts I of the oil. The part possessing the property of volatility in the highest degreewill burn first, and so on,assuming that theburner is cold when the oil is lighted. down the inclined plate and overflows from one tray to the other the heat of the burner is increasing, and by the time the heaviest portiouof the Oil has reached the bottom tray the heat of the burner will have attained a degree sufiicient to consume this heaviest portionof the oil.

-The burner whenin use may be placed in the fire-box of an ordinary stove or range or As the oil flows in any other suitable receptacle. ,In the drawings a receptacle 12 is shown provided with air-holes 12 at the bottom for draft purposes. Having thus described my invention, what -I claim is- 1. A crude-oil burner comprising a series of separated trays arranged one above the other anddistinct the one from the other, an inclined plate mounted on the uppermost rounding the bolts and interposed between the tray and the plate, all the trays. having .fianges surrounding their outer edges, the

trays between the inclined plate andthe lowermost tray, having raised parts in their hottoms provided-with openings for the overflow from'on'e tray to the other, the raised parts being only of sufiicient height to maintain a shallow body of liquid on the bottom, the trays between the inclined plate and the bottom tray, having supporting-legs whereby the trays are separated, substantially as described. p

2. A crude-oil burner comprising a series of trays, each tray except the lowermost having legs engaging the tray below, whereby the trays are suitably separated, the trays being separate and distinct the one from the other, whereby the number used may be, regulated at will, the trays being provided with flanges around their outer edges, and each tray except the lowermost having overflow-openings surrounded by raised parts to maintain a shal-' low body of liquid on the bottom of the tray. In testimony whereof I aflix my signature in presence of two witnesses.
